The story revolves around Ajayan (Mohanlal), who, after having tried his luck in different cities around the world, comes back to his village to look after his ageing mother Ammukutty Amma (Sheela) and to get her love and the nostalgia of his growing up years. There, he starts a company for producing agricultural equipment and earns his living as a farmer. One day a boy comes and meets Ajayan claiming to be his son. Ajayan who used to boast himself as a womanizer in his youth is believed to be the boy's father by all villagers. Ammukutty Amma starts getting to like the boy and they form a very friendly relation and eventually she starts accepting the boy as Ajayan's real son, though Ajayan ferociously rejects the boy's claim and dislikes him. The boy is persuaded by Ammukkty Amma to get close with Ajayan and subsequent events soften Ajayans attitude towards the boy. Ajayan then set forth to enquire about the real identity of the boy and travels to Chennai. He is absolutely sure that he is not his father as the real truth is his stories about adventures with the woman were actually lies to get the admiration of his friends. The climax shows us that Ajayan accepts the boy as his own son.
